Re: [MW:29882] Welder qualification as per Chapter IX of ASME B31.3.

By Materials & Welding

In my opinion, only bend tests as stipulated in QW -452 of ASME Section 09 is applicable.  

 

And the interpretation is as below,

In ASME B31.3 Chapter 09, the requirements are as below

1.       K328.2.1 Qualification Requirements.

           e) Mechanical testing is required for all performance

qualification tests.

 

And if we refer to ASME Section 09, QW-302 TYPE OF TEST REQUIRED, QW-302.1 Mechanical Tests which in turn reference to QW-452. 

Thus, only bend test is considered as mechanical testing for welder qualification tests.

Dear Experts,

As per ASME B31.3  Chapter IX Welding, does performance qualification requires all mechanical testing to do be done including tensile, bend, impact, lateral expansion to be measured apart form RT.

As per Clause K328.2.1(e)

(e) Mechanical testing is required for all performance
qualification tests.

Pl share your valuable inputs.

best regards

Heat tint (temper) colours on stainless steel surfaces heated in air // Heat tint

By Materials & Welding
Introduction The colour formed when stainless steel is heated, either in a furnace application or in the heat affected zone of welds, is dependent on several factors that are related to the oxidation resistance of the steel. The heat tint or temper colour formed is caused by the progressive thickening of the surface oxide layer and so, as temperature is increased, the colours change.   Oxidation resistance of stainless steels However, there are several factors that affect the degree of colour change and so there is no a single table of colour and temperature that represents all cases. The colours formed can only be used as an indication of the temperature to which the steel has been heated. Factors affecting the heat tint colours formed Steel composition The chromium content is the most important single factor affecting oxidation resistance. The higher the chromium, the more heat resistant the steel and so the development of the heat tint colou...

The Schaeffler and Delong diagrams for predicting ferrite levels in austenitic stainless steel welds

By Materials & Welding
Introduction Ferrite is important in avoiding hot cracking in during cooling from welding of austenitic stainless steels. 'Constitution diagrams' are used to predict ferrite levels from the composition by comparing the effects of austenite and ferrite stabilising elements. The Schaeffler and Delong diagrams are the original methods of predicting the phase balances in austenitic stainless steel welds. Nickel and chromium equivalents A 'nickel equivalent' is calculated for the austenite stabilising elements and a 'chromium equivalent' ferrite stabilising elements. These are used as the axes for the diagrams, which show the compositional equivalent areas where the phases austenite, ferrite, martensite (and mixtures of these) should be present. Although intended to show the phase balance of weld fillers, these diagrams can also be used to illustrate the phase balance of the 'parent' material. There are different diagrams for dif...
